Application September 16, 1946, Serial No. 697,219

1 Claim. 1

My invention refers to a hot air compartment heating system wherein afuel stoker is employed.

The primary object of my invention is to provide, in conjunction with astoker fan, means for supplying a forced feed of air to lazydistributing flues of a system wherein certain of said fiues fail tosupply the proper amount of heat due to their position or length.

A further object of my invention is to provide pipe controlled meanscommunicating with an air delivery duct and the stoker fan air pipewhereby a forced feed air is directed to one or more of the heaterflues.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claims, itbeing understood that such changes in the precise embodiment of theherein disclosed invention may be made as come within the scope of theclaim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

The drawing illustrates a side elevation of a heating system embodyingthe features of my invention with parts broken away and in section tomore clearly illustrate structural features.

Referring by characters to the drawings, l indicates a hot air furnaceprovided with a stoker equipment 22 of any standard type. The stoker isprovided with the usual worm drive 3 for delivering fuel from the stokerhopper to the burner portion thereof. The stoker is also provided withthe usual motor driven fan 4 having a stoker air pipe 5 connecting thefan and the burner proper.

The dome of the furnace is provided with the usual series of hot airdistributing flues 66 which fiues communicate with various rooms of adwelling or compartment, indicated by the numeral A.

An intake air duct 1 also communicates with the compartment and thebottom portion of the furnace all of which mechanism is of standardtype.

My improved construction embodies an air suction pipe 8 having anupwardly inclined mouth 8' in communication with the intake duct 1 andthe opposite end of this pipe is directly connected to the centralportion of the fan casing 4'.

One or more of what might be termed defective or lazy fines, isconnected by a comparatively restricted feed pipe 9, which pipecommunicates with the stoker air pipe 5 and one of the hot air fiues 6.

The forced feed pipe 9 is also provided with a branch pipe 9', of whichpipe communicates diin the pipe 6, the valve 10 will be moved to open adirect passage of air from the stoker air pipe 5 to said flue, whereby aportion of the air drawn by the fan from the duct 1 will be dischargeddirectly into the lazy flue to create a forced feed of hot air from themouth of the flue 6 to the compartment under which conditions thedefective flue is remedied. In instances where none of the fiues arelazy the flow of air from the forced feed pipe 9 may be directed intothe dome of the furnace, whereby all fiues will receive the maximumamount of hot air delivered to the dome of the furnace by the auxiliaryforced air draft.

It is understood, in some instances I may, without departing from thespirit of my invention, employ the suction pipe mechanism withoutcombining it with the air supply pipe 9, or visa versa.

I claim:

In a hot air compartment heating system having a furnace including anair intake duct communicating with the bottom of the furnace, hot aircompartment fines of difierent lengths communicating with the furnacedome, a fuel stoker associated with the furnace fire pot having a fan,an air supply pipe communicating with the fan and fire pot of thefurnace; the combination of an air forced feed for certain of the hotair compartment flues, comprising a restricted forced feed air pipeconnecting the stoker air supply pipe and one or more of the lazycompartment flues adjacent the furnace dome, a branch pipe connectingthe restricted forced feed pipe and furnace dome and a valve in saidforced feed pipe for selectively directing air from the restrictedforced feed pipe to the dome or to a lazy hot air flue, whereby anauxiliary current of hot air is discharged from the lazy pipe fluemouth.
